Importance of Kothprashaman Dravya in Ayurveda

Kotha (Urticaria) is a skin disorder recognized in Ayurveda that manifests as red, itchy rashes on the skin due to an imbalance in the doshas, primarily Pitta and Kapha. Kothprashaman Dravya refers to medicinal substances that help in alleviating urticaria and similar allergic reactions by addressing the root cause, detoxifying the blood, and restoring dosha balance. These herbs and formulations play a crucial role in cooling the body, reducing inflammation, and enhancing immunity.

Dosha-Dhatu Physiology of Kotha

Kotha is primarily caused by an imbalance in the doshas—Pitta and Kapha. According to Ayurveda, urticaria originates due to the accumulation of toxins (Ama) in the blood, leading to hypersensitivity reactions.
